More specifically, I would like to ask if the point about Vatican II is true, and what in particular this might be referring to.
No it's not, because throughout history masses have been celebrated outside of Churches. Vatican II may have made some reference to masses outside of established church buildings, but it certainly didn't allow a NEW practice in doing such a thing.
In fact, from the very beginnings of the church masses were held both outside and in homes (some of which had the interiords converted into "church buildings"). It wasn't until at least the 3rd century that it became legal for Christians to build structures explicitly as "churches" in the city of Rome.
And masses have always been said outdoors in the cases of armies on the move, or even large bodies of people. I once attended a mass at which Pope John Paul II was SUPPOSED to preside (unfortunately, he became ill and couldn't travel) at which 15,000 young men attended mass outdoors led a cardinal (incidently, I DID later get to see the pope in person at a papal audience! :D). I have also attended masses outdoors in context of being in the military and engaged "in the field" where no church structures existed... and that's no different from armies during, say, the crusades, when masses would have to be said for armies that were on the move through areas where no churches existed.
